On the basis of atomic number and mass number, elements can be classified as isotopes, isobars and isotones.

Let’s discuss about isotopes with some common examples.

Hence, in an atom the atomic number is also equal to the number of electrons.Radioactive krypton-81 is the product of reactions with cosmic rays that strike the atmosphere, along with some of the other isotopes of krypton. Krypton-81 has been used for dating old (50,000- to 800,000-year-old) groundwater.Krypton-85 is a radioisotope of krypton that has a half-life of about 10.75 years.However, it is inevitable that krypton-85 is released during the reprocessing of fuel rods from nuclear reactors.The atmospheric concentration of krypton-85 around the North Pole is about 30 percent higher than that at the Amundsen–Scott South Pole Station because nearly all of the world's nuclear reactors and all of its major nuclear reprocessing plants are located in the Northern Hemisphere, and also well-north of the equator.
